specific Embodiment 2

[0056] The specific embodiment 2 of the roller type overrunning clutch of the present invention, the difference between the roller type overrunning clutch in this embodiment and the specific embodiment of the above-mentioned roller type overrunning clutch is only: as Figure 9 and Figure 10 As shown, the force application seat 8 is arc-shaped, and there are six force application seats 8 at intervals along the axial direction of the roller overrunning clutch, and each force application seat 8 is integrally fixed on the end surface of the outer ring 1 . The force application seat 8 includes two sides perpendicular to each other, one of which constitutes the stop part of the force application seat 8, which is arranged parallel to the end surface of the outer ring 1 and forms a gap with the corresponding end surface of the outer ring 1 ; The other side constitutes the fixed part of the force seat 8, which is formed by extending the end face of the corresponding end of the outer r...

Abstract

The invention relates to a pin roller type overrunning clutch. The pin roller type overrunning clutch comprises an inner ring, an outer ring, a pin roller and a holder, wherein one of the inner ring and the outer ring is a star wheel provided with a working surface; the holder can rotate around the axis of the pin roller type overrunning clutch; the pin roller is embedded in a holding hole of theholder and can move with the holder in a circumferential direction under the pushing action of the wall of the holding hole; a force applying seat is fixed to the star wheel; an ear part is fixedly arranged on one of the force applying seat and the holder, and an avoidance hole is formed in the other one; the ear part stretches into the avoidance hole in the radial direction of the pin roller typeoverrunning clutch; the avoidance hole has an activity space in which the ear part moves in the circumferential direction; a magnetic adsorption structure or a magnetic repelling structure is arranged between the ear part and the avoidance hole and is used for applying a wedging acting force to the holder; and the wedging acting force is used for driving the pin roller to move toward the wedgingdirection, and thus, the reliability of the pin roller type overrunning clutch is improved.

Description

technical field [0001] The invention relates to a roller type overrunning clutch. Background technique [0002] The overrunning clutch, also known as the one-way clutch, is a device that automatically combines and disengages using the change in the relative rotational speed of the main and driven parts, or the change in the direction of rotation, and can only transmit power from one direction. [0003] At present, multiple springs or springs and ejector pin structures are commonly used in roller overrunning clutches (such as the roller overrunning clutch disclosed in the utility model patent with the authorized announcement number CN203756794U) to push the rollers into the wedging area. During the process, there are the following problems: (1) Due to the inconsistency of the manufacturing length and pitch of each spring, the spring force on the rollers is uneven, and the wedging and disengagement of the rollers are inconsistent, resulting in premature stress failure of some ...
